I don't think 10 seconds of continuous trim input is really a "short burst." It is a myth that MCAS runaway and "normal" runaway are so different that a pilot would not be able to recognize MCAS runaway as a runaway stabilizer. I would be willing to bet that when the final reports come out that there is no discussion where the pilots discuss the possibility of runaway stabilizer and determine it isn't one because of the slightly different behavior. My opinion is that lack of focus of training for runaway stabilizer for decades due to the exceedingly rare rate of occurrence is the reason that it wasn't recognized.
Also, a "normal" runaway stabilizer does not necessarily mean that electric trim won't work. In fact, the runaway stabilizer NNC directs the pilots to use the electric trim among the first steps.
You are right. I did overlook this. Clear cut case of crew incompetence indeed.
Right - because Boeing had been so forthcoming and transparent with max pilots about mcas, which would have helped them diagnose the problem in the first place. What a joke!
Some of you are truly unbelievable. First, Seahawk I never said anything about crew incompetence. And 748capt I hope your user name isn't your occupation. Neither crew needed to diagnose the problem. They needed to recognize the symptoms and determine what NNC to perform. It doesn't matter to the crew if the runaway is caused by MCAS or a flying unicorn living in the trim motor.
For all the nitpicking about what a "real" runaway stabilizer is vs an MCAS runaway, I am willing to bet money that neither final report contains a conversation amongst the crew where they bring up the possibility of runaway stabilizer but determine that it isn't because of MCAS behavior.
I don't blame the crews, I blame inadequate training on runaway stabilizer. Boeing shares that blame because they introduced a new cause for runaway stabilizer but didn't alert the customer airlines. This disclosure may have led to it being more of a focus in differences training.
